What is the purpose of `dnsmasq` running listening on `127.0.0.1` interface?Assigning IP addresses is the role of DHCP server, not DNS server. This instance of dnsmasq doesn't play a role of DHCP server, since there's no subnet specification in the configuration file. Moreover, no requests from other machines can arrive from 127.0.0.1 which is the interface this instance is listening on.
